ANNOUNCEMENT | FilSwan Incentivized Proton Testnet

Today we are excited to announce our 2nd testnet — Proton testnet for FilSwan.

After months of hard work, we are excited to announce that we will be launching the 2nd FilSwan Proton Testnet on June 10, 2022. Proton Testnet 2 is a technology upgrade from Testnet 1. It is aiming to enhance the usability of the FilSwan cross-chain experience as a user/developer/service provider and reduce the cost.

This one-week-long testnet 2 is designed for developers, crypto enthusiasts, service providers, and anyone looking to participate in the Web3. It allows users to stress-test the recently released features that focused on real-world storage(like small file storage, multi backups to service providers), NFT minting, DAO governance, and application development.

The 1st testnet in March validated the proof of concept of FilSwan cross-chain functionality. During the two-weeks test, we have over 250+ participants and generated over 13,000 NFTs on the OpenSea Testnet. Thanks to the community, Testnet 1 is a great success!

1. The total bonus pool

All participants will have the opportunity to share a total of 500,000 Swan Credits, 100TB Datacap (storage providers only), and 85 $FILs.

Swan credits can be redeemed for Swan tokens (once generated).

Swan credits, Datacap, and $FILs will be distributed according to participants’ rank on the leader board.

2. Duration

EST: June 10, 2022, 09:00:00- June 16, 2022, 09:00:00

UTC + 8: June 10, 2022, 21 :00 :00- June 16, 2022, 21:00:00

3. How to participate

There are two tracks in Testnet 2:

Track One: User Track

Users will be invited to upload files, mint NFTs, and pay for storage using stable coins (test)using either the WebApp or API (link to API doc, SDK)

i. Access: or use the MCS SDK API portal to participate in

ii. Upload at least three files

iii. Mint at least 3 NFTs

Track Two: Storage Service Provider

You can also participate in testnet 2 as a Filecoin storage provider. Storage providers will be scored based on the deal success rate, and total deal amount.

i. Install the Swan Provider tool to perform related Settings

Details refer to:

Swan Provider Tools ( MultiMiner version)

ii. Complete at least one data file receiving process

  1. WID

In the FilSwan network, every single request is a “task”, and every cross-chain task has a unique WID (an 84-byte code) in the smart contract.

The task types include but are not limited to computing, storage, bandwidth, and access to repositories.

For instance, if a user wants to host a website in Web3, all s/he needs to do is submit a static website hosting request to the IPFS. First, s/he needs to submit an IPFS storage task that includes a CID. Afterward, FilSwan will generate a specific WID for this task and submit it to the smart contract.

2. Multi Storage Provider

Proton Testnet’s multichain storage application enables users to backup files automatically to multiple storage providers.

FilSwan discovery service helps match available swan providers globally. The selected provider will provide backup services.

3. Small File Merging

Multi-Chain Storage allows users to send small-sized files (as small as 10KB), and merge them. The small file merging function makes small file backup more reliable and less likely to be rejected by storage providers, which can save up to 95% of the gas cost.

For more information about FliSwan features, please check our docs here:

A total amount of 500,000 Swan credits will be available for all participants to share. Track One (User Track) and Track Two (Storage Provider Track) will split the credits pool 7 : 3.

Credits available for the user track = 350,000 credits.

Credits available for the Storage Provider Track = 150,000 credits.

The distribution of credits will depend on each individual’s participation score.

To ensure a fair distribution of rewards to all participants in testnet 2, we are using some quadratic formulas to determine the rewards that each participant earns for their contributions to the network.

1. Rewards for the Top 3 Users

1st place: 40 FIL

2nd place: 30 FIL

3rd place: 15 FIL

How the score ranking is calculated:

2. Rewards for the Top 3 storage service providers

1st place: 50 TB Datacap

2nd place: 35 TB Datacap

3rd place:15TB Datacap each

How the score ranking is calculated:

Score =average deal success rate * total deal amount

3. Swan Credits

How scores and credits are calculated

3.1 Rewards for all the users

Credit Rewarded = (Total Credits Available in this track * 0.5 ) / (Total # of Participants) + (Total Credits Available in this track * 0.5 ) * Individual Score / (sum of all participant score) = (350,000 * 0.5 ) / (Total # of Participants) + (350,000 * 0.5 ) * Individual Score / (sum of all participant score)

3.2 Rewards for all the storage serve providers

Score =average deal success rate * total deal amount

Credit Rewarded = (Total Credits Available in this track ) * Individual Score / (sum of all participant score)= 150,000 * Individual Score / (sum of all participant score)
